If you don't want to remove g77 it's enough to make sure it is not on
your path (mv or rename the binary temporarily). For some reason if
distutils finds it it will use it in preference to gfortran regardless
of the commandline --fcompiler option. (This was the case when I first
started with scipy - it might be fixed now)

Alternatively you could just use g77 instead of gfortran (ok as long
as you use it for everything) - the instructions would be pretty
similar except you might need to find libg2c instead of libgfortran
for the extra path to the BLAS and LAPACK options for umfpack.

I got the impression gfortran is more actively developed and supported
though and seems to be the recommended option.

Not sure about the ATLAS stuff - I never had much luck with Ubuntu
packages as I said so I tend to build it myself and keep everything in
a seperate directory.
